Adolescents' friendship quality and over-time development of well-being: The explanatory role of self-esteem.

INTRODUCTION: The mechanism underlying the positive longitudinal link between adolescents' friendship quality and their well-being is unclear. The present study was performed to investigate whether this longitudinal association between friendship quality and well-being was established via adolescents' global self-esteem, and to examine gender differences in these associations. METHODS: Online questionnaire data were collected in two waves (in Spring 2018 and Spring 2019) from 1298 Dutch adolescents aged 11-17 years (mean age 13.7 ± 1.1 years, 53.2% girls). RESULTS: Multigroup path analyses revealed a significant indirect effect between friendship quality and well-being over time via global self-esteem for girls. For boys, significant direct effects of friendship quality on global self-esteem and well-being were found, but no significant indirect effect. CONCLUSIONS: The findings indicate that higher-quality friendships improve boys' global self-esteem and well-being directly, and that they affect girls' well-being indirectly and positively, by improving their global self-esteem. These results suggest that preventive and intervention-based strategies for the promotion of well-being during the developmental stage of adolescence should incorporate focus on friendships, global self-esteem, and gender specificities.

Longitudinal associations among adolescents' internalizing problems, well-being, and the quality of their relationships with their mothers, fathers, and close friends.

RATIONALE: Internalizing problems (i.e., depressive and anxiety symptoms) are known to decrease adolescents' well-being, but knowledge about potential underlying mechanisms is limited. The qualities of adolescents' most proximal relationships with their parents and close friends are expected to play a role in the association between adolescents' internalizing problems and well-being. OBJECTIVE: The present study was conducted to 1) investigate the indirect longitudinal association between internalizing problems and adolescents' well-being via the quality of adolescents' relationships with both their mothers and fathers and their close friends, and 2) test whether our findings were gender invariant. METHODS: Data were collected via online questionnaires in two waves at a 12-month interval from adolescents attending three secondary schools in the Netherlands (N = 1298; M age = 13.7 years, 53.2% girls). The data were analyzed using a two-wave cross-lagged panel model in R. Multigroup analyses were performed to examine the gender invariance of the findings. RESULTS: After controlling for baseline levels, results showed that (1) girls, but not boys, who reported more internalizing problems at T1 had lower well-being at T2; (2) girls and boys who reported more internalizing problems at T1 had lower-quality relationships with their mothers, fathers, and close friends at T2; and (3) boys, but not girls, who reported higher-quality friendships at T1 had higher well-being at T2. However, no significant indirect effects between internalizing problems and well-being via the quality of adolescents' relationships with their parents and close friends were detected. CONCLUSIONS: The current study contributes to understanding internalizing problems as an important risk factor to the quality of adolescents' proximal social relationships (parents, friends) and their well-being. The findings support the importance of building high-quality relationships, particularly friendships, and recommend future research to study adolescents' internalizing problems and well-being including gender-specific examinations.

Evaluating the psychometric properties of the mental health continuum-short form (MHC-SF) in Dutch adolescents.

BACKGROUND: Mental health is increasingly viewed as the presence of various aspects of well-being rather than just the absence of mental illness. The Mental Health Continuum-Short Form (MHC-SF) is a 14-item instrument that assesses mental health, focusing on emotional, psychological, and social well-being. The present study examined for the first time the psychometric properties of the Dutch version of the MHC-SF among adolescents, focusing on its factor structure, internal consistency, construct validity, and gender and age factorial invariance. METHODS: Data were collected from a school-based sample of 1175 adolescents (53.4% girls) aged 11-17 years (M = 13.7; SD = 1.1). Participants completed an online questionnaire in the classroom during regular school hours. Statistical analyses to evaluate the factor structure, internal consistency, construct validity, and gender and age factorial invariance were performed in SPSS and R. RESULTS: Using confirmatory factor analyses, a satisfactory-to-good fit was obtained for the three-factor model (emotional, psychological, and social well-being). The MHC-SF scores showed good internal consistency (Cronbach's alpha = .91) and results supported convergent and divergent validity. Finally, the MHC-SF showed gender and age factorial invariance. CONCLUSION: The current psychometric evaluation indicates the MHC-SF is a reliable and valid instrument to assess multiple dimensions of well-being among Dutch adolescents. The instrument can be applied for research purposes and in clinical practice.
